Way to long a thing to listen to it all but as soon as he said bras serve no purpose, i realized he was FULL OF SHIT.
If a woman has small boobs,maby not so much,but if she has big 1's and trys to go braless, there is the cause of her neck pain,back pain and so on.
Muscles support the boobs and keep them up right while the woman is young to a point but if allowed,the boobs will drop,sag,and cause pain.
i know a lady that was looking into reduction surgery to try to cope with the upper back pain prompted by her large natural breast.
Nothing makes a woman look less kempt than going braless.

I've never heard that theory
